Title: Feed water regulating method of exhaust-heat steam generator
Inventor: KURISUTOFU RUUFUTEI
IPC: F22D5/30
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To perform the transfer from a normal operation start-up drive state to a controlled load drive state without pressure drop by supplying heat inside the exhaust gas flow of a gas turbine to a flow-through regulator for feed water flow. SOLUTION: By a three-component control, a level regulator 13 changes the set value Sollein , using the flow-through regulator 14 for feed water flow, which is subordinated to a superordinated level regulator 13. The water level in a drum 6 is always regulated to the set value Soll, regardless of interfering effects. In this method, heat QAG in the exhaust gas flow of a gas turbine is supplied to the flow-through regulator 14 for feed water flow. With this, overall water level regulation is performed and the transition from the normal operation start-up drive state to the controlled load drive state can be performed without pressure drop and without changing the structure of a regulation cycle.

Title: Manufacture of low-phosphorus al-killed steel
Inventor: AOKI NOBUHIDE
IPC: C21C7/06
Filed: 1982-04-16
Abstract: PURPOSE:To extremely efficiently manufacture high-grade low-phosphorus Al-killed steel, by smelting pig iron melt together with necessary adjutant raw materials into a state having low C content with upper-blown oxygen and bottom-blown gas, vacuum degasifying the formed steel to deoxidize and decarburize it, adding Al to it, and then continuously casting it. CONSTITUTION:Pig iron melt tgether with necessary adjutant raw materials is bottom- blown with gas during and/or after being refined with upper-blown O2 in the converter furnace which enables the upper blowing of O2 and the bottom blowing of gas to make steel of [C] below 0.07%, and the resulting steel melt is tapped under an undeoxidized condition. The undeoxidized tapped steel melt is then treated in a vacuum degasifier to perform decarburization, deoxidation and the adjustment of necessary components. From the time when [C] comes close to an objective value with the progress of the decarburizing reaction of C+O CO in the vacuum degasifier, Al is added in installments to reduce [O] down to about 0.002-0.005%. Thereafter, the steel melt after being treated in this way is formed into a cast piece of predetermined size by a continuous casting process. The formation of Al2O3 clusters is little in this continuous cast piece, and said cast piece is a low-phosphorus Al-killed one extremely excellent in quality as compared with a conventional Al-killed cast steel piece.

Title: Control system of synchronous motor
Inventor: MAGARIYAMA YUKIO
IPC: H02P25/026
Filed: 1984-03-31
Abstract: PURPOSE:To control a synchronous motor having preferable characteristic corresponding to that of a DC motor by advancing the phase of a current command in response to the phase difference detected by a phase difference detector. CONSTITUTION:A phase detector 8 detects a phase difference theta between a current command LW* and an armature current IW in phase W. A speed amplifier 1 amplifies the difference of a rotating speed N from a speed detector 6 from a speed command Nref, and outputs as a current command Iref. A vector controller 2' inputs the command Iref, the direction theta of a main magnetic flux from a pole position detector 5 and a phase delay theta detected by a phase difference detector 8, decides current commands IU*, IV*, IW* of the phases U, V, W, and outputs to a current amplifier 3. Thus, the armature current is crossed particularly to the main magnetic flux in the range of all rotating speeds.

Filed: 1984-04-03
Abstract: PURPOSE:To prevent the damage of a recording element or the deterioration of recording quality when the control part operated by software is operated abnormally, by providing the circuit of hardware for limiting the width of a driving signal within a predetermined range. CONSTITUTION:Even when CPU is abnormally operated and a timer starting signal TK is brought to a DC state while strobe signals STB1-4 outputted to a strobe signal driver 213 from the third output port 205 of an output IC200, a timer 210 alternately outputs a timer on-operation signal TD and time-up signal TA. A counter 211 also outputs count signals C1, C2 and a decoder 212 also ouputs decoder output signals DC1-DC4 to the strobe signal driver 213. Because the strobe signal driver 213 outputs the AND signals of the decoder output signals DC1-DC4 and the strobe signals STB1-4 to a thermal head as strobe signals STB1'-4', the outputted strobe signals STB1'-4' become same to the strobe signals STB1-4 in a normal state and the driving of heat generation elements R1-R1728 are performed so as not to be different from a normal state.
